TJA1028TK/5V0/20/1 是恩智浦(NXP)推出的一款LIN收发器(Single LIN transceiver),集成一路驱动器和一路接收器,专为车载局域网(Local Interconnect Network, LIN)节点设计。该器件支持标准的5 V供电,拥有低功耗和宽温度范围,适用于车内环境苛刻、对可靠性要求高的应用场景。小型HVSON-8 (3×3 mm) 封装利于在空间受限的电子控制单元(ECU)上实现高密度布局。
该收发器在典型工作状态下表现出低功耗特性:活动模式下工作电流约 4.5 mA,而静态或休眠模式下电流可低至 45 μA,有助于整车待机功耗优化。接收器具有 200 mV 的滞后,有利于滤除总线上短脉冲干扰和切换抖动。工作电压窄范围(4.9–5.1 V)提示设计时应保证电源稳压与去耦良好,避免电源瞬态导致通讯异常。器件可在 -40 ℃ 至 +150 ℃ 环境下工作,但在系统设计时应结合热阻、PCB 散热条件以及封装热特性进行热管理评估,确保长期可靠性。
TJA1028TK/5V0/20/1 以其宽工作温度与较强的静电防护能力适配车规级应用。在车载环境设计中,建议开发阶段实现 ESD、EMC、热冲击与机械应力的验证,确保整车级稳定性。最终产品应按汽车行业相关标准进行测试与验证,满足整车厂的质量与安全要求。
总结:TJA1028TK/5V0/20/1 是一款小型、低功耗且适应车载高温环境的 LIN 单通道收发器,适用于车身控制与各类空间受限的 LIN 节点。合理的电源滤波、PCB 布局与热管理是确保其在实际系统中稳定运行的关键。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
